Overview
Overview
Cartridge length × outside diameter: 20-inch catalog length; outside diameter unverified. Partial or unverified dimensions. Nominal size classes may differ from measured end-to-end dimensions.
FT-FTC-20BB20 is listed as a 20-inch Big Blue filter cartridge with a 20-micron rating. Here, cartridge length and filtration grade are two separate specifications.
Match both values to the installed cartridge. The 20-micron designation does not establish chlorine removal, and the shorter FT-FTC-20BB listing is not the same length.
